Abstract:
Three cases of patients with transient epileptic amnesia (also known as pure amnestic seizure) are described. In two patients it was the unique seizure type and represented de novo epilepsy occurring in the elderly. In the third patient it coexisted with long standing complex partial seizure of mesial temporal lobe origin. The problems associated with the diagnosis and the main clinical features are discussed. In addition the underlining pathophysiological mechanisms are considered. It is argued that this seizure type is likely to be under-diagnosed and that further research is needed as the presence of TEA has significant implications for clinical and surgical management.

Amnesia
The severity and duration of memory loss vary depending on the type and underlying cause. Amnesia is classified into two main types: retrograde and anterograde.
Retrograde amnesia is marked by the loss of memories formed before the onset of the condition. Patients may recall distant past events but often forget those occurring shortly before the incident.
Anterograde...

Seizures: Classification
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:
